One of the attendees in our Building Network Automation Solutions online course sent me this question:

While building an automation tool using Python for CLI provisioning, is it a good idea to use SDK provided by device vendor, or use simple SSH libraries Netmiko/Paramiko and build all features (like rollback-on-failure, or error handling, or bulk provisioning) yourself.

The golden rule of software development should be “don’t reinvent the wheel”… but then maybe you need tracks to navigate in the mud and all you can get are racing slicks, and it might not make sense to try to force-fit them into your use case, so we’re back to “it depends”.
